Reacting to Tuesday's move by the e-commerce giant to hike the minimum wage for all its U.S. employees to $15 per hour, White House economic advisor Larry Kudlow told CNBC, "Good for them. I'm in favor of higher wages."

The Vermont senator, who unsuccessfully sought the 2016 Democratic presidential nomination, has been bashing Amazon founder and CEO Jeff Bezos for making billions and billions of dollars personally and paying his employees low wages.

Sanders, who is considered a contender for the 2020 Democratic nomination, last month even went so far as to introduce legislation, called the Bezos Act, to tax corporations for every dollar that their low-wage workers receive in government health-care benefits or food stamps.

However, what Bezos has announced on wages "is not only enormously important for Amazon's hundreds of thousands of employees, it could well be, and I think it will be, a shot heard around the world," Sanders said Tuesday.

Bezos himself took to Twitter to thank Sanders for his praise. "We're excited about this, and also hope others will join in," the Amazon CEO said.

"More people working and prospering ... is not inflationary. It's a good thing not a bad thing," said Kudlow, adding it looks like Bezos made a "business decision," and "he's a pretty good businessman."

Trump has not only taken Amazon to task over taxes. He's also directed his ire at Bezos personally as owner of The Washington Post, which the president feels is biased against his administration.
